The biggest technical obstacle with the Millenium Tower is how to get to the top of the building. Current elevator technologies only allow a maximum of about 80 stories, and passengers will need to transfer elevators to reach further. For a tall building like this one, how do you fit enough elevator shafts to take people to the top given the small floor plate?

Taipei was able to build 101 because of some innovative technological squeaks in the design. During its construction, Taipei was rocked by a major earthquake, but the building was still sound. However, embarking on such an endeavour is costly and risky. That's why there aren't that many supertalls in earthquake-prone areas, especially in Japan.

hehe, you just said that it will ruin HK's skyline but now you just like it to be built there.^.

It's more where you're gonna build the tower. I just based my opinions on the photo and I hate the idea of having this tower right infront of Central. But I wouldn't mind if they build it somewhere. Anyway, The Bionic Tower has the same concept as Millennium Tower and the plan was to build it on the water off Mt. Davis which is in the western part of HK Island. I would mind if The Millennium Tower would be built there.

But why is the limit 80 floors when we have the destroyed WTCs at 110 floors, the new ICC at 118 floors and the burj dubai at 160 floors (double this so-called limit)? Agree though, the fact that it was to be built in water might represent some difficulties.

Skylobbies will allow two sets of elevator shafts reach the higher floors above the 80-storey limit. But for a building the height of the Millennium Tower, how many skylobbies will be needed to get people to the top? There comes a point where the floorplate cannot fit 3-4 sets of elevator shafts for a 200-storey structure.

One possible invention to solve the problem is the horizontal elevator. An elevator will move up 80 stories, transfer horizontally to another shaft, then continue to move up.

I don't think there's even a horizontal lift and that would be cool if it did. Anyway, since the Millennium Tower is a conical structure, most likely they'll place the elevators in the centre.

But some skyscrapers will have elevators on the sides or the tip like the Hopewell Centre in Wan Chai for example.

Hopewell Centre has a set of elevators in its core. The 1 elevator on the side is purely for sightseeing purposes rather than for the regular office workers. I used the inside ones to get to the top and I found the sightseeing one when I left.
